The ND1460 1.4 inch exit neodymium high frequency compression driver has
been designed for use in high quality sound systems. The pure titanium
diaphragm is produced in house and has been developed to assure
unmatched transient response. The diaphragm assembly is made by joining
the former directly to the titanium dome using its upper bend edge. In
comparison with a usual straight former joint, the driver design assures
extended frequency energy transfer giving improved response linearity
and unparallel reliability. This feature facilitates proper motion
control of the dome in real working conditions. A proprietary treated
Nomex former is used as Nomex shows a 30% higher value of tensile
elongation at a working operative temperature (200°C) when compared to
Kapton. Moreover, this proprietary former material is also suitable for
use in high moisture content environments. By carefully using
elementary pieces of neodymium magnets, Eighteen Sound engineers have
developed a powerful neodymium magnet assembly capable of reaching
19KGauss in the gap in compact and lightweight structures. The motor
structure, throughout the precisely coherent phase plug with 3
circumferential slots and copper ring on the pole piece, reduces
inductance effects and distortion. Four top plate air ducts have been
designed to act as a loading chamber for the diaphragm, implementing mid
band distortion and response figures. The custom designed O-ring
creates a tight seal between the plate and the cover assuring air
chamber loading. Excellent heat dissipation and thermal exchange are
guaranteed by the direct contact between the magnetic structure and the
aluminum cover which leads to a lower power compression value. The
